Rihanna: My Mom Yelled at Me Over Naked Instagram Pictures

The 25-year-old singer tells Elle U.K. that her mom had some choice words for her over a few racy Instagram posts.

"I'm not afraid of any person in this world but my mother, I'm terrified of her!" Rihanna told the magazine. "She called me two days ago and reeled me in about two naked pictures [my friend] Melissa put up on Instagram, a sneak peek from a photo book she's making about me."

Rihanna's Instagram topics of choice typically tend to be Chris Brown, smoking weed, or showing off her, um, assets, but apparently it's the nudity that gets her mom worked up.

"She went crazy on me, I was like, embarrassed," she continued. "I felt like I got my a-- whipped in front of my class at school! She humbled the f--k out of me."

Just this week the "Stay" singer uploaded a provocative photo showing off her new Prada boots, but the focus wasn't exactly on her new heels since RiRi wasn't wearing any pants or a top.
